l .To l1f/ZZ whom it may concern:

Be it known that I, BERTRAM SARRETT, -a

l citizen of the United States, residing at Camden, in the county ofBenton and State 4of l Tennessee, have invented certain new and usefulImprovements in Cradle-Rocking Attachments, of which the following is aspecification.

The object of my invention is to provide an improved construction ofautomatic rocking attachment for cradles so arranged that it will fitcradlesof different lengths and provided with means' whereby more orless power 'may be imparted from the motor mechanism to the cradlewhenever desired.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreHecting the result reference is to be had to the following descriptionand accompanying drawings, in which- Figure 1 is an end view of myinvention. Fig. 2 is a top plan view4 of the attachment. Fig. 3 is aside elevation. Figs. 4 and 5 are detail views illustrating the meansfor 'attaching the cradle-rockers to the supportingframework.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the referencenumeral 1 designates thesupporting-framework, which comprises two end bars 2, designed todirectly support the rockers of a cradle, and two side bars or lon'tudinal bars 3, which are made in. extensib e sections 3 and 3b,adjustabl connected together, so that the framework may be extended tosuit cradles of diiierent sizes. In the present instance the sections3EL of the side bars have rigidly secured thereto metallic or woodenplates 4, which extend inwardly to form upper and lower guides 4a, andthe ends of said sections are secured together by spaced-apart and lowertransverse braces 5, as shown in the drawings. The sections 3b areconnected together at their ends by a transverse brace 6 and are fittedto slide between the transverse braces 5 and between the flanges orguide members 4it of thel plates 4. Adjusting1 or clamping screws 7extend through eit er one or both of the sections 3a and are designed toimpinge against the sections 3b, so as to maintain the two sections intheir different adjusted positions. A

date rockers o diiferent. curvatures.

i The motor vmechanism (designated 8) is mounted in a casing 8a of anydesign secured to oneside of the framework, and preferably the motormechanism is located at the middle of the framework longitudinallyconsidered. The motor mechanism 8 is referably of the spring type, thespring 9 o which is intended to be wound up by means of a hand-lever 10.y Through a suitable train of gearing, which includes master-wheels 11and `governor-shaft 12, providedvwith goveiner-balls 128L and acounter-shaft 13, provided with pmions 14 and 143,'meshin respectlvely,with the master gear-whee and t e governor-shaft, motion is impartedfrom the spring .to the counter-shaft 13, and the latter carries at oneend an eccentric 15.

I-he eccentric 15 is provided with two socketapertures 16, which aredifferent distances from its center, as shown in the drawings. A

detachable crank-pin 17 is designed to enter l either one of the saidsocket-apertures and is intended to secure to said eccentric one end ofapitman 18. The other end of said pitman 1s detachably secured to one endof the rockers 19 of the cradle 20. Preferably the pitman isextensible-that is, it is" constructed in two sections 18a and 18",arranged to telescope and be held at different extensions by means of aset-screw 18C. By this means the pitman ma be.extended to accommllli- Te counter-shaft which carries the eccentric is preferably provided withay ratchet-wheel 21, with which a hand-operated pawl 22 is adapted toengage 'in order to stop the motor mechanism atl any desired time-forinstance, when the child in the cradle falls asleep. The brake mechanismconstituted by the ratchet and pawl mechanisms is not indispensable,however, as the eccentric and pitman themselves may be utilized to bringthe cradle to a standstill by merely stopping the cradle with the pitmanon the center. Then should the child awake and move or roll from oneside of the cradle to the other it `will so shake the cradle as tothrowI the pitman off the center and again start the mechanism. By thismeans the 4startingis rendered automatic in a sense in that it does notrequire personal supervision or any manipulation to start it.

From the foregoing description, inconnection with the accompanyingdrawings, it will be seen that I have provided a cradle attachment whichwill mechanically rock a ICO cradle whenever desired and which will ac'commodate itself to cradles of different -sizes and diierent curvaturesof rockers. The different a ertures in the eccentric are provided sothat more power may be given, if desired, by attaching the pitman to theeccentric nearthe center of the same. This may be important when thechild grows and lbecomes so heavy that the mechanism will cured to theend bars of the supporting-` frame by means of headed studs 25, securedlto the rockers and designed to enter keyhole-slots 26 in lates 27secured to and pro-v jecting upward y from the end bars of thesupporting-frame. It will be seen that the slots widen at their upperends, so that the rockers may be detached readily from the suporting-rame by moving them upwardly to s 'de the studs upwardl in thesots and then sprin g the plates o the studs.

While i? drawin s show the motor located at the left-han end of themachine, as

shown in Fig'. 1,4 it is of course to be understood that my invention isnot limited to this exact location of. the motor, as it may belandpreferably is located at the right-hand side of the framework.

Havin thus described the invention, what is claime as new is A deviceofthe character described comprising a framework constituted 'of endbars desi and ongitudina bars constructed in sections respectivelyconnected to ,the endbars, two of said sections being provided at theirends ed to Sup ort the -rockers of a cradle'.

with upper and lower transverse braces embracing the other lsections andbeing also provided near said ends with inwardlyex j tending upperandlower plates constituting guides and clamping-screws designedto'extend inwardly to impinge against the yother sections,pglatessecured to the end bars of the framewo and extending upwardltherefrom each of said plates being provi ed with a keyhole-slot, acradle embodying rockers provided with headed studs designed to :be

lnserted through the enlarged portions of said slots whereby they may beretained and guided therein, a motor mechanism supported on saidframework,` and a detachable and adjustable pitman connection betweenone of the rockers of the cradle and said motor mechanism. o

In testimony whereof I ai'liX my signature in presence of two witnesses.
